 Some instructive observations on the supposed anti-malarial influence exerted by sunfiowers have been made by the editor of the Monthly Journal of Pharmacy, who has found that quarter of an acre of suntlowers will exhGle in the form of vapor sixty-fve gallons of water day. This was in June, at place where the mean midday tempera- lure was only seventy degrees Fahren- heit.

 By observing how far the sun has to sink beneath the horizon before the topmost summit of the air is cut off from is rays, the conclusion has been arrive at that the greatest upward limit of twilight is some 378,000 feet, or nearly seventy-one miles above the sea level. It is well-known fact that, by observing the earth's shadow on the moon during the time of lipses, the inference came to be held by astrono- mers that the atmosphere must be suffi- ciently dense to produce twilight tor at least 240,000 feet away from the earth s surface.

 German scientists have discovered a worm that devours steel rails. Rail- road accidents at Hagan led to an in vestigation of the rails. After six months had elapsed the surface of the rails appeared to be corroded, as # by acid, to the extent of 100 yards. The rail was taken up and broken, and il was perceived that it was literally hol- lowed out by thin gray worm. It is two centimeters in length and of the size of the prong of silver fork in cir. conference. It is of light gray colol and on the head carries two little glands filled with a corrosive secretion which is elected every ten minutes upon the iron.
 Observations at Rothamsted. tho celebrated farm of Sir John B. Lawes in England, show that with an annual rainfall of little less than thirty-twt iuches, each acre of land receives ovel fourteen pounds of pure chlorine every year in the rain water, or as much chlo inc as is contained in twenty-fou pounds of common salt The sulphur, acid which the soil receives from th' same source amounts to upwards 0 seventeen pounds per acre annually and the ammonia between two ant
 three pounds. Thus it will be seen tha
 the rain possesses distinct fertilizini
 properties apart from the necessar
 moisture which it supplies.-M ! l ' Te11eY.
